OK, so I found out what's going on, but I really need a wiring diagram to fix it.
There are 2 primary power leads going into the LKM. The one that shorted to ground and has melted insulation has no power to it but the other one does. Either a fuse, fusable link or relay must have blown. There isn't anything in the glove box for those, and I don't know where else to look.
